Krebs Cycle

The process in which 2 pyruvic acid molecules from glycolosis is converted into 8 NADH, 2 ATP, and 2 FADH2. Each yields NADH yields three ATP through the electron transport chain and each FADH2 yields 2 ATP. Oxygen is required to create a proton gradient so NADH and FADH2 so it could be converted into ATP by ATP Synthase, an enzyme. Since this requires Oxygen, this is a form of aerobic respiration. ATP synthase is located on the mitochondria membrane of eukaryotes and on the plasma membrane of prokaryotes.

I hate everyone who does not know what the Krebs Cycle is!

menstrual cycle

The span of 28 days, any of which, 5-7 could be the worst of a mans life. During these days, woman cramp, ache, and bitch. The combination of these makes for one fussy little lady which in many cases may lead to a breakup if an excessive ammount of time is spent with the periodee.

"Wow, Katie looks good today"
"U'r my fucking boyfriend Johnny!!! You like her more than me, I thought I meant something to you... You want her you can have her. You always talk about her I bet. Never talk about me to her I bet. Or to any of your friends. I bet you dont even think about me. *starts crying* I'm so sorry, i love you, never leave me. I'm sorry. I'm sorry. *Starts crying again*"
"Wow, I wish I had a menstrual cycle just like you!"

Skurman Cycle 

The reboot cycle on a public vending machine that clears stucks products. Can be forced by unplugging the machine.

Yeah, my diet coke got stuck in the machine so I pulled the power plug and forced it into a Skurman cycle. It spat that can right out.

rum cycle

Noun: refers to to the reoccuring cycle in which one gets way too drunk, wakes up, feigns some type of recovery and then submits to the need to begin drinking again thus arriving at the place where one started.

Despite popular belief, once started there is not an end to the rum cycle only an enlargening of the circle.

The name is actually a misnomer as from a personal prospective one seems to start from the same spot but has actually sunken a bit.

I was heavy into the rum cycle by my third day of vacation in Costa Rica.
